So you are saying: when set up to spec, i.e. everything aligned with the markers on the cage, the chain rubs on the cage when in small / big, because the cage cannot move further inboard?
In that case, I don't understand why spacing the crank further outboard won't help?
Are you running an axle with a lip, or not?
Out of interest, as that bike shares the same rear end as my Caad9, does it look like the FD is too far towards the back of the bike?

The front mech does go far enough in so that the small ring sits inside the limits of the cage. It is the difference between that and the big at the rear that makes the chain rub. I tried fitting a spacer already and it didn't resolve the issue. However, seeing as i've tried everything else 5 times it might be worth giving it another go. I'm worried though that the amount of movement needed might be more than the axle has spare.
Has anyone else spaced out Hollograms before? What did you use?

By forward do you mean rotate it front end in, rear end out? We've tried that. As it is there's no room for movement between the mech and the band-on adaptor, it's a 'perfect' snug fit.
There is currently room for it to go lower but only by 1mm or so. We have tried it set lower and encountered the same problem though.
